Ok I got the fix.
I added the '[ ]' on the variable in the form, so the code
looks like this:
<select name="email[]" size="4" multiple id="email">
<option value="1 Accounting">1
Accounting</option>
<option value="1 Adjustments">1
Adjustments</option>
</select>
Then I went to the script that processes the form and change
my variable definitions to this:
$FTGemail = implode(',',$_POST['email']);
